Summary: This study evaluated the use of locally accessible herbal plants as natural remedies for managing Parascaris equorum infection in horses. The herbal extracts showed efficacy in reducing the number of parasite eggs in fecal samples, with Nigella sativa exhibiting the highest effectiveness.

Summary: Anthelmintic resistance has become increasingly prevalent in equine nematodes, particularly in cyathostomins, Parascaris spp., and Oxyuris equi. Resistance to benzimidazoles, pyrimidines, and macrocyclic lactones has been documented in cyathostomins and Parascaris spp. The shortened egg reappearance period (ERP) observed in recent studies raises questions about the development of anthelmintic resistance, and more research is needed. Routine monitoring of anthelmintic efficacy is recommended.

Summary: This study used data on equine strongyle communities and found that horse age and parasite egg excretion have a certain impact on species richness and the Gini-Simpson index. The differences between different operations are also important factors affecting species richness and dominance. In addition, within-host diversity also has a significant impact on overall diversity. Finally, analysis of necropsy data identified a network of positive co-occurrences between the four most prevalent strongyle genera.

Summary: In the past three decades, the egg reappearance periods (ERPs) for macrocyclic lactone anthelmintics in horses have become significantly shorter. This study used computer simulations to evaluate the impact of shortened ERPs on the efficacy of ivermectin and moxidectin against equine cyathostomins. The results showed a substantial loss in anthelmintic performance due to the shortened ERPs.

Summary: Equines were previously thought to be infected by two morphologically indistinguishable ascarid species, but species discrimination can be achieved through karyotyping. Most sequences previously identified as P. equorum in GenBank actually represent P. univalens, highlighting the need for molecular markers to differentiate between the two species.

Summary: The prevalence of strongyle and Parascaris equorum infection is low in the studied working horse population in Egypt, with evidence showing no resistance to macrocyclic lactones or benzimidazole in strongyles. Anthelmintic treatment in the past year was associated with reduced likelihood of strongyle infection, while age and gender were factors associated with Parascaris equorum infection.

Summary: The study revealed high rates of nematode infection in horses in the Moscow Region, with Parascaris equorum being the most common. The egg reappearance period indicated the need for additional monitoring of anthelmintic resistance for effective control.

Summary: This study evaluated the precision of current standard operating procedures for counting the luminal adult cyathostomin populations in horses and investigated the effects of fixative and storage duration on the magnitude and precision of worm counts. The results showed that luminal cyathostomin worm counts had moderate to high precision, and there were no significant effects of fixative and storage duration on the counts.

Summary: This study found that reducing the intensity of anthelmintic treatment for foals and mares in equine stud farms did not have significant negative health consequences, despite higher parasite egg counts in some foal groups.

Summary: This study evaluated the effects of P. equorum infection on oxidative stress and gene parameters in donkeys, showing infected donkeys with higher antioxidant capacity and oxidative damage levels, as well as elevated enzyme levels in the internal organs. After effective treatment with moxidectin, the fecal egg count in P. equorum infected donkeys significantly decreased.

Summary: This study aims to assess alterations in hematological and biochemical parameters in pure Arabian horses infested with internal parasites. The results showed slight variations in hematology values compared to reference values, while serum biochemistry values were within the normal range. The study suggests that the given nutrition compensates for the damage caused by parasites in Arabian horses, providing useful diagnostic indices.

Summary: Due to increasing drug resistance, traditional parasite control strategies for adult horses are no longer effective and recommendations need to be re-evaluated. The major parasites of adult horses have shifted from large strongyles to small strongyles and tapeworms, while foals and weanlings are still primarily affected by ascarids. Customized parasite control strategies and special attention to horses under 3 years old will enhance animal welfare and offer economic benefits.

Summary: This study reports for the first time the adaptive evolution and divergence trend of P. univalens in different hosts, revealing that metabolic adaptive evolution has occurred over the past few centuries. It is of great significance for understanding host-parasite interactions.
